Speaking to a joint meeting of Congress, Israeli Prime Minister Benjamin Netanyahu showed the world what strong diplomatic leadership looks like in facing the threat of a nuclear Iran.  It was a historic speech, and Netanyahu used the opportunity to make the case that the alterative to the deal under negotiation is not “no deal,” it is “a better deal.”

He also took great care to assuage critics in the Democratic Party, calling Senate Minority Leader Harry Reid “my friend” and congratulating him on his recovery from injuries in a recent accident, citing the old saying on it being “hard to keep a good man down.” He thanked President Obama effusively for his support of Israel, citing specifics, but also noting that some matters would stay secret, possibly forever. In other words, he disarmed those critics who portrayed his visit as political and a slap in the face of President Obama.

A complete transcript of the speech is available here.

Citing the holiday of Purim, beginning tomorrow night, which celebrates the escape of the Jews from a plot against them in Persia, he placed the current situation in vivid historic context:

 Today the Jewish people face another attempt by yet another Persian potentate to destroy us. Iran's Supreme Leader Ayatollah Khamenei spews the oldest hatred, the oldest hatred of anti-Semitism with the newest technology. He tweets that Israel must be annihilated -- he tweets. You know, in Iran, there isn't exactly free Internet. But he tweets in English that Israel must be destroyed. 

For those who believe that Iran threatens the Jewish state, but not the Jewish people, listen to Hassan Nasrallah, the leader of Hezbollah, Iran's chief terrorist proxy. He said: If all the Jews gather in Israel, it will save us the trouble of chasing them down around the world. 

But Iran's regime is not merely a Jewish problem, any more than the Nazi regime was merely a Jewish problem. The 6 million Jews murdered by the Nazis were but a fraction of the 60 million people killed in World War II. So, too, Iran's regime poses a grave threat, not only to Israel, but also the peace of the entire world. To understand just how dangerous Iran would be with nuclear weapons, we must fully understand the nature of the regime. 

He laid bare the threat Iran poses to America and the rest of the world:

Beyond the Middle East, Iran attacks America and its allies through its global terror network. It blew up the Jewish community center and the Israeli embassy in Buenos Aires. It helped Al Qaida bomb U.S. embassies in Africa. It even attempted to assassinate the Saudi ambassador, right here in Washington, D.C.

In the Middle East, Iran now dominates four Arab capitals, Baghdad, Damascus, Beirut and Sanaa. And if Iran's aggression is left unchecked, more will surely follow.

So, at a time when many hope that Iran will join the community of nations, Iran is busy gobbling up the nations.

(APPLAUSE)

We must all stand together to stop Iran's march of conquest, subjugation and terror.

(APPLAUSE)

Now, two years ago, we were told to give President Rouhani and Foreign Minister Zarif a chance to bring change and moderation to Iran. Some change! Some moderation!

Rouhani's government hangs gays, persecutes Christians, jails journalists and executes even more prisoners than before.

Last year, the same Zarif who charms Western diplomats laid a wreath at the grave of Imad Mughniyeh. Imad Mughniyeh is the terrorist mastermind who spilled more American blood than any other terrorist besides Osama bin Laden. I'd like to see someone ask him a question about that.

And he brilliantly exposed the flaws in the apparent policy of the Obama administration cooperating with Iran to fight ISIS.

Don't be fooled. The battle between Iran and ISIS doesn't turn Iran into a friend of America.

Iran and ISIS are competing for the crown of militant Islam. One calls itself the Islamic Republic. The other calls itself the Islamic State. Both want to impose a militant Islamic empire first on the region and then on the entire world. They just disagree among themselves who will be the ruler of that empire.

In this deadly game of thrones, there's no place for America or for Israel, no peace for Christians, Jews or Muslims who don't share the Islamist medieval creed, no rights for women, no freedom for anyone.

So when it comes to Iran and ISIS, the enemy of your enemy is your enemy.

Citing publicly available information, he demolished the logic behindthe proposed deal with Iran:

Absent a dramatic change, we know for sure that any deal with Iran will include two major concessions to Iran.

The first major concession would leave Iran with a vast nuclear infrastructure, providing it with a short break-out time to the bomb. Break-out time is the time it takes to amass enough weapons-grade uranium or plutonium for a nuclear bomb.

According to the deal, not a single nuclear facility would be demolished. Thousands of centrifuges used to enrich uranium would be left spinning. Thousands more would be temporarily disconnected, but not destroyed.

Because Iran's nuclear program would be left largely intact, Iran's break-out time would be very short -- about a year by U.S. assessment, even shorter by Israel's.

And if -- if Iran's work on advanced centrifuges, faster and faster centrifuges, is not stopped, that break-out time could still be shorter, a lot shorter.

True, certain restrictions would be imposed on Iran's nuclear program and Iran's adherence to those restrictions would be supervised by international inspectors. But here's the problem. You see, inspectors document violations; they don't stop them.

Inspectors knew when North Korea broke to the bomb, but that didn't stop anything. North Korea turned off the cameras, kicked out the inspectors. Within a few years, it got the bomb.

Now, we're warned that within five years North Korea could have an arsenal of 100 nuclear bombs.

Like North Korea, Iran, too, has defied international inspectors. It's done that on at least three separate occasions -- 2005, 2006, 2010. Like North Korea, Iran broke the locks, shut off the cameras. 

The threat is not just to Israel, it is the US:

And by the way, if Iran's Intercontinental Ballistic Missile program is not part of the deal, and so far, Iran refuses to even put it on the negotiating table. Well, Iran could have the means to deliver that nuclear arsenal to the far-reach corners of the earth, including to every part of the United States. 

He laid down what should be the conditions for loosening the sanctions (which he noted are all the more effective thanks to the collapse of oil prices):

Before lifting those restrictions, the world should demand that Iran do three things. First, stop its aggression against its neighbors in the Middle East. Second...

(APPLAUSE)

Second, stop supporting terrorism around the world.

(APPLAUSE)

And third, stop threatening to annihilate my country, Israel, the one and only Jewish state.

President Obama is going to have a very hard time selling his deal to Congress.
